caption_attribution_description: English: Verso side of the papyrus fragment (Berlin, Staatliche Museen P. 21319). The fragment found in Egypt belonged to a tropologion, the part marked in red shows a modal signature which indicates the mode "echos plagios devteros" of the following Theotokion (a troparion in honour of the Mother of God). This signature and some sporadic signs of an early ekphonetic notation are in fact the only form of musical notation, the scripture can be classified as semi-cursive book script.
context_page_description: The liturgical book called Octoechos contains a repertoire of hymns ordered in eight parts according to the eight echoi. Originally created as a hymn book with musical notation in the Stoudios monastery during the 9th century, it is still used in many rites of Eastern Christianity. The hymn book has something in common with the book tonary of the Western Church. Both contained the melodic models of the octoechos system, but the tonary served simply for a modal classification, while the book octoechos is as well organized as a certain temporal of several eight week periods and the word itself means the repertoire of hymns sung during the celebrations of the Sunday Office.
